Cigarette smoking is a significant contributor to global warming!

I have always been fascinated with those who try to look over the horizon and see things that are coming at us.

Population growth is straining the Earth's resources to the breaking point, and educating girls is the single most important factor in stabilizing that. That, plus helping women gain political and economic power and safeguarding their reproductive rights.

I think it's harder for people than it should be. But as more and more of us become carbon neutral and change the patterns in our lives to be part of the solution instead of part of the problem, we are now beginning to see the changes in policy that are needed.

We sometimes emphasize the danger in a crisis without focusing on the opportunities that are there.

Fifteen per cent of the population believe the moon landing was actually staged in a movie lot in Arizona and somewhat fewer still believe the Earth is flat. I think they all get together with the global warming deniers on a Saturday night and party

When it comes to climate, we can all make a big difference. At the most basic level, don't let denial go unchallenged and win the conversation on climate.
